CULTIVATOR.

SPECIFICATIO forming part of Letters Patent No. 353,000, dated November 23, 1886.

Application filed May29, 1886.

To all whom it may concern;

Beit known that I, WILLIAM S. PATEs, of Alton, inthe county of Madison and State of Illinois, formerly of LTonesburg, in the county of Montgomery and State of Missouri, have invented a certain new and useful Improvement in Cultivators, of which the following is a full, clear, and exa-ct description, reference being had to the accompanying drawings, forming part of this specication, and, in which l Figure l is a side elevation of my cultivator, part in section. Fig. 2 is a top view of the same. Fig. 3 isa detail perspective view of the horizontal bail attachment on which the vertical bail has lateral adjustment. Fig. 4 is a detail perspective view of thevertical bail provided with a bolt on which the clevis has vertical adjustment.' Fig. 5 is a detail perspective view of the draw-head and clevis that couple the bails to the gangs. Fig. Gis aperspective view of the forward hanger-arch, showing its attachment to the beams from which it is suspended, and a horizontal bail With'its bell-crank arm and push-spring.

My invention relates to improvements adapt.- ed to both ridingv and walking cultivators t0 facilitate their adjustment by the operator when either riding or Walking; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims. y

Referring to the drawings, in which similar letters of reference indicate like parts, Arep` resents the rear extension of the tongue, 'and B theframe, to thelongitudinal inside bars, B', of which the gang-elevating levers C and segment-racks D are secured. B2 represents the outside longitudinal bars of said frame.

' The lever C is pivoted at C' to the baseplate of the rack, and is provided with a stiff elbow-bar or short arm, C2, which descends. vertically from said lever and has a pivotbearing, C3, that is adjustable in elongated slots E in the arms of the fork E2 ofthe rodlink E. The rod terminates at its front end with a secondfork, E3, whose4 arms embrace an upwardly-extending arm, F', and-.has pivoted connection at F2 with both the vertical arm F' of the horizontal bailF of the gang attachment, (see Figs. 8 and 6,) and with a vertical spring-bearing rod, H. The upper Serial No. 203,636. (No model.)

end of the spring-bearing-rod pas-ses through and is loosely held in an eyebolt, H', that is .secured to the aforesaid longitudinal bars B laterally adjusted by a screw-bolt, G2, that passes'through a perforation, G3, in the vertical bail and finds lateral adjustment in an elongated slot, F3, 'in the plate fof the horizontal bail, and is secured by a nut, g'. By this means the gangs are adj usted laterally and rigidly secured in said adjustment by said screw-bolt when the nut is tightened thereon. Y G is the vertical draft-bolt attached to the vertical bail, which gives setting play for the vertical adjustment of the gangs, which adjustment is clamped by the clevis J, that has a pair of cheek-plates, J', which are closed by a set-screw, J2: The clevis-bracket isxsecured between the fore ends ofthe gang-beams by bolts J3, and has flanged 'grips J4, that clamp over the edges of' said beams.

K are the gang-beams, operated, when used as a walking cultivator, by the handles L,

that are bolted to them and braced by bars L',

and when as a riding-cultivator by the operation of the lever in conjunction with the'stittbail coupling for elevating and depressing the gangs, as will be more fully described hereinafter.

M are the shovel blocks or brackets that couple the shovels N to the bent beams.

O is the double-crank frame, forward arch, or

hanger, on which the horizontal hails have their pivoted bearings, and on-which are hooked the draw-rods P. The arch is secured to the longitudinal bars B' of the frame bybearingI-plates O. (See Fig. 6.) A pendent vertical hitchbar Q is provided with a series of holes, Q', for the attachment of the whiftletreesat adjustable heights of draft.

Brace-rods R extend from the spindles "or arms O of the hanger-arch to the main axlearch S, to which they are bolted where said axle grasps the shoulders of the spindles T,

that carry the Wheels U. V represents a spring at the rear of the tongue, that carries the seat WV. A pawl, X, is operated for Withdrawal by the rod Y and trigger Y and returned to its engagement inthe rack under the projectile influence of the spring Z.

In operating the cultivator it will be seen that the lever with its pendent extension adj usts the position of the spring-bail gang-coupling attachment,which is of peculiar construction, so that When in the projected position shown in dotted lines at l the stift' bail elevates the gangs even to the extent, if required, ofwithdrawing the shovels from the ground under the influence of the depression of the lever, and when in the withdrawn position shown in dotted lines at 2 the gangs are correspondingly depressed.

A projecting lug or bolt on the pendent arm C2 of the lever is adjustable in an elongated slot in a rod-link that has pivoted connection with the vertical arm of the horizontal bail F. This arm has a stift elbow-connection with the bail, and is pivoted at sid elbow to the arml O of the hanger-arch, so it is evident that when the lever is depressed and the head of the bailarm is projected, as shown in dotted lines, the stiff-bail coupling of necessity must raise the gangs, and so also, vice versa, by the elevation ofthe lever the shovels are depressed. The push-spring I helps the operator to make the adjustment in both cases. It Will be seen (see Fig. 2) that this bail-coupling is distinct in its application from a sleeve-coupling having two separate bearings on the shaft of the hanger-arch, and so obtains a much rnier and better braced hold than any sleeve could have; also, the bail has an elongated slot that gives means for the lateral adjustment of the gangbeam, and the vertical bail G carries a bolt With sufficient play for the coupling-clevis to give vertical adjustmentto said gangs. Thus when used as a riding-cultivator the operator is enabled easily to command and vary the elevation of t-he gangs without alighting from his seat or stopping the team. This is a feature of considerable importance where the change of level and the nature of the soilvary, as they frequently do in different parts ot' the same iield; also, by its adjustable bail in contradistinctioii to a sleeve-coupling it possesses facilitiesr for both lateral and vertical adjustment, which, being regulated at the draft end of the gangbeams, avoids in a large de* gree the diiiculties arising from the side draft, Ste., in the Work of the shovels.

Although so Well adapted for a riding-cultivator, it may also be used as a Walkingcultivator, either with or Without the use of its levers, and in that case the adjustable springbails will still greatly aid the operator in handling the gangs; also, when used as a Walking-cultivator the lug from the pendent arm of the lever, Which at other times is adjusted to the position desired and firmly secured by a tight nut in the elongated slot E' of the rodlinlc E, may, by loosening the nut, become self-adjusting in the slot and give more freedom to the operator in the use of the handles.4

I claim as my inventionl. The combination of a suitable support ing-frame, a lifting-lever, a hanger provided with a horizontal spindle, a horizontal bail having an upwardly-extending arm, a hinged springrod, a rod connecting the lever with the arm, a clevis,J, and a vertical bail, G', by which the clevis and horizontal kbail are connected together, substantially as described.

2. The combination of a suitable supporting-fra1ne, a hanger provided with a horizontal spindle, the horizontal bail F, hinged on the spindle,a vertical bail, G, sliding sidewise on the horizontal bail, and a clevis, J, connected to the horizontal bail by means ot the vertical bail and adjustable vertically 'on the latter, substantially as described.

3. The combination of a suitable support ing-frame,V a hanger provided with a horizontal spindle, the horizontal bail F, having an upwardly-extending arm, F', and hinged on the spindle, a vertical bail, G, to the rear of the horizontail bail and sliding sidewise thereon, having rear arms provided with a vertical bolt, G', and a clevis, J, to the rear of the vertical bail and sliding vertically thereon, substantially as described.

4. The combination of the horizontal bail having an upWardly-extending arm, a bearing-rod, a spring surrounding the bearing-rod,

.and a lever connected to the arm, substantially as described. d

5. The combination of a hanger provided with a horizontal spindle, a horizontal bail having an upwardly extending arm and hinged to the spindle, abearingrod, a spring, a lever, and a rod connecting the lever with the arm and bearing-rod, substantially as described.

6.
